Abstract

The invention relates to a device for correcting radial run-outs during the fabrication of cylindrical parts (9). The device comprises a rotating spindle (4) which can be driven and a chuck (5, 6) which is fastened to the spindle (4) and accommodates a cylindrical part (9). The invention is characterized in that the chuck (5, 6) can be transversally displaced on the spindle (4) relative to the spindle axis (3) by being actuated with a defined force. In addition, a measuring device (12) is provided in order to determine a radial run-out of the cylindrical part (9) relative to the spindle axis (3). The invention is also characterized in that a final control element (14) can be controlled according to the measurement result of the measuring device (12) in order to generate the defined force which thus displaces the chuck (5, 6) relative to the spindle (4). The device permits the middle axis (13) of a cylindrical part (9) to be centered opposite the spindle axis (3) in a fully automatic manner.
